Whining noise from transmission (4R70W) or rear end
I have a whining noise in 1st and 2nd gear when accelerating from a stop or slow roll and it stops when it reaches 20mph and switches to 3rd or 4th (OD). I believe its coming from the transmission but could it come from the rear gears also? The gears are the stock 3.27 so I doubt it's that. No whining noise in park or neutral. Any ideas?
